'Ihe operation of the machineillustrated in the drawings is as follows:

' assume that the outer housing contains a body of Water and that some of saidgivater has passed through the apertures into the inner drum. Assume also that clothes have been placed in the inner drum and that it is to Wash said clothes. Rotary or oscillatory A motion Will be applied to the gear wheel l() in' any suitable manner and. because said gear. Wheel is mounted on the trunnion l said trunnion will be rotated or oscillated about the lstationary trunnion 4 whereby the inner drum C, which is secured to said trunnion, will be actuated. Then the machine is in operation the `Water is violently agitated, but even if some of, said Water findsV its Way through the openings in the side Walls of the outer housing B through Which the trunnions l extend, said Water cannot Work intov Ytheinterior of. the bearings as toV do this it Would be necessary for said -Wa'ter to travel over the hub ofl the gear Wheel l0. It is also plain that itis impossible for theV oil or grease from the bearing to Work its Way into the inner drum C. Y

` To eliminate theV opportunity rfor even a slight amount of Water to find its :Way

through the openings in the side Walls of the Youter housing B, I employ semi-circularV lWater sheds ll, one otvvhich is secured to. the inside face of each of saidside Walls of said outer housing in'such position that it partially surrounds the Ytrunnion l Which extends through ythe opening in said side' The sheds 1l are trough-shaped` inv cross section (Fig. I), andk are intended to catch most of the Water which may be Wall.

desired to rotate or oscillate said inner drum splashed about in close proximity to the openings mentioned.

While I have described my improved bearings as being a part'of a clothes Washino' machine, it is to be understood that said carings may be used With machines for per,- orming many other duties, such, for instance, as fur Washing and dyeing machines,

Y and machines for chemically vWashing vari-v ous articles. f

I claim: 1

l. A bearing, for a machine lhaving astationary outer housii'igY and amovable' inner receptacle, comprising" a member' secured to :said inner receptacle and' lextended outuf'ardythrough avvallof said outer housing, a supporting member` secured tosa'id outer` housing, and an inwardly proj eeting member on said supporting member, said memberon said inner receptacle being provided With a recess into which said second mentioned memberv extends whereby saidY inner receptacle isY supported, andrall portions of said i "recess into @which saidV second `mentioned trunnion extends whereby saidinner receptacle is supported.
